Most perverted thing ever done

From what I read from a forum, it seems that secretly cumming into a colleague’s or friend’s shoes / bra (taken from their gym bag) seems to be a popular antics. 🤔

The worst I have read is cumming into their food or drinks. 🤮

After reading those stories, I think I felt like a saint. The most perv thing I done/doing is probably just masturbating to my wife cousin’s photos. 😄

So what’s your story?
